An online friend of mine stumbled upon a couple of curious stickers while hiking on recent hikes. One was on Garnet Mountain, which I hiked about 11 months ago, and another was on Ken Point, a peak along the Desert Divide. Since I didn't see the sticker on Garnet Mountain when I was there, I can only surmise that it was placed there fairly recently (less than a year).
Does anyone have any insight on these stickers? Please feel free to comment below.

Update 10/11/2010: Added another one from the same friend who keeps finding these.
